Project: small PCB hw and fw design with 4 AD9106 DDS chips an Ardunio nano controller plugged into the board with the firmware.
Goal: generating 16 pcs. of sine signal at a given phase relationship (with at least 1 deg resolution 0-360 deg range) to each other up to (at least) 40MHz range. Provide a simple text based control interface for setting up the (common) frequency and phase of each signa...
I want to use an Arduino controller for a specific home automation application. The Arduino will turn on/off a TV via remote IR signal based on the status of an external input. Here are the details.
Eternal Input - the external input will be a normally open 2 wire circuit that will momentarily close (cycle) with a frequency of .1 to 1 second.
Programming Switch - this...
Vehicle Passenger Monitoring System using Open Source Electronics
I need someone to design and build a electronics systems which can monitor number of passengers getting in and out of a vehicle and also measure the distance that each passsenger travels. I need inputs from at least two different sensors to be double sure. I want it to be built with open source electronics such as Aurdino and compatible sensors which are easily available on ebay, amazon etc. The d...

build a simple technical element, 1v current to contral a 12v 35W current
I am far from an expert so excuse my incorrect naming of things.
I have a 12V 35W heating element (for my 3d printer) that I want to control (on off) with a technical element. I would have a 1v current going into the element (from some components on my 3d printer PCB, where I know it turns on only if the heater should come on) and whenever this iv current flows, the 12V current should be permi...
